One can still read about its functionality on the Blacet "Cool Old Stuff" history page. Its application was for creating sounds ranging from the sublime to the monstrous. The DSC2000 took great advantage of the SN76477's capabilities. John Blacet brought the SN76477 into the commercial synthesizer world with his excellent "Dark Star Chaos" module, a discontinued and still much-sought-after design produced by his company, Blacet Research.

In this application, the SN76477 was primarily used as a source for syncable gates, triggers, and LFO signals, but it did also feature the sweepable digital noise generator as a signal output. In his book "Build a Better Music Synthesizer", Thomas Henry published a design for a controller module, dubbed "The SuperController" based around the SN76477. There were a couple of serious synth applications developed for it. The SN76477 didn't die its ignoble death in vain.
Somewhere between the mid '80s and early '90s (I'm not sure when) Texas Instruments terminated the SN76477. Some were music related, others were for just making revving engine, steam engine, explosion and gunshot effects. There were a few kits out there for hobbyists. It was also featured in other items, more often than not, toys. The SN76477 appeared in many a video game of the late '70s and early '80s, supplying players with bleeps, bloops and swept noise as they vanquished pixellated aliens dropping from the skies. But it still exists out there in the wild - a few supply houses on the internet still list it, and it's been known to inhabit parts bins all over the world waiting for just the right application. If you're new to Synth DIY and have never heard of the SN76477 IC, there's a good reason - it's long been out of production.
